The most common materials used in fittings produced is carbon steel, stainless steel, cast iron, aluminium, copper, glass, rubber, the various types of plastics, etc..In addition, fittings, like pipes, for specific purposes sometimes internally equipped with layers of materials of a completely different quality as the fitting themselves, which are “lined fittings”. The material of a fitting is basically set during the choice of the pipe, in most cases, a fitting is of the same material as the pipe.

The ends of all buttweld fittings are bevelled. The shape of the bevel depending upon the actual wall thickness. This bevelled ends are needed to be able to make a “Butt weld”.


Cost-Effectiveness: Plastic pipe and fittings, like those used in black waste systems, are generally less expensive than metal alternatives. The lower material cost combined with easier installation can result in significant savings for both materials and labor.

Lightweight: ABS and PVC are lightweight materials, making them easier to handle and install, especially in overhead or hard-to-reach locations. This can reduce installation time and the need for heavy lifting equipment.

Chemical Resistance: Black waste pipe fittings are resistant to a wide range of chemicals typically found in household and industrial waste, ensuring the system remains intact and functional over its lifetime.

Noise Reduction: Plastic pipes tend to transmit less noise than metal pipes, which can be an advantage in residential settings where quiet operation is desired.

Non-Conductive: Unlike metal pipes, plastic waste pipe fittings do not conduct electricity, which is a safety advantage in areas where there might be electrical grounding concerns.
